Hotel Michael, Resorts World Sentosa – Singapore

To provide a 3-storey high Green Wall system to be installed along the beverage alley, which serve patrons of the Casino located within Hotel Michael.

Anchoring pilasters were installed directly onto the wall for the installation of nine 3-storey high green walls, alternating between water features, along the beverage alley beside the Hotel. To allow selected plants to be firmly established, VGMs comprising a geotextile bag filled with soil-less lightweight planting media were pre-planted in a nursery environment. On site, the VGMs were secured in metal support frames and mounted onto the pilasters, with a drip irrigation system installed. The VGM modular green wall system allows individual modules to be dismounted and remounted, facilitating easy maintenance and replacement.

The green walls keep the ambient temperature along the alley cool and provide an aesthetically pleasing green ambience to an otherwise concrete narrow build-up area.

Raffles Dubai Hotel – Dubai UAE

To provide sub-soil drainage for the landscape roof garden of the hotel complex.

VersiCell sub-soil drainage cells were positioned over the prepared grounds of the roof followed by a geotextile filter fabric layer and then the planting soil. The cavity provided by the drainage cells facilitates the efficient drainage of water preventing water-logging and promoting healthy plant growth in the elaborate roof garden of the Hotel.

15 Joan Road – Singapore

To provide extensive planting system to enable planting on top of existing car park polycarbonate shelter in short lead time.

An aluminium sheet was installed over the rooftop to reinforce the polycarbonate rooftop to accept installation of the MEP^® Trays. The lightweight and robust MEP^® Trays were pre-planted in a nursery environment prior to installation. By using locally sourced plant species selected for their hardiness, colour and height in individual trays, desired designs and patterns were easily achieved.

The self-contained trays with water storage compartments and a capillary wick system support sustained plant growth with minimal maintenance. The system includes a support plate with anti-root overflow outlet covers, capillary wicks, geotextile filter, confinement grid, joining and fastening pegs, and a drainage network consisting of base connectors and drainage pipes installed independent of the trays. Rodent barriers were installed at the corners of the perimeter trays to prevent rodent pests from infesting the space between trays.

MEP^® Tray facilitates the almost instant greening of rooftops and allows associated benefits of the green roof to be immediately realised.

Republic Polytechnic, Singapore

To provide waterproofing membrane protection and efficient sub-soil drainage under the landscaped roof areas on the 20ha site of the campus.

VersiCell lightweight interlocking modules, positioned over the waterproofing membrane, offers immediate protection for the membrane whilst other installation works were carried out. High compressive strength of the modules made it possible for light machinery to be placed on top without compromising the membrane below. A geotextile filter fabric is installed over the VersiCell and planting soil placed on top. The drainage cells provide the necessary cavity beneath the planted areas to efficiently discharge excess sub-soil water and prevent water-logging on the landscape roof. The resultant lush greenery on the campus grounds has earned the Polytechnic the nickname of “Campus in the Park”.

HDB Car Park – Holland Drive, Singapore

To facilitate planting on the RC rooftop of the Car Park to provide a Green Roof both attractive and effective in reducing urban heat island effect.

VersiDrain 25P drainage and water retention trays were installed over the waterproofing membrane. Geotextile filter fabric was then laid over the VersiDrain 25P and a lightweight inorganic planting media, EnviroMix GR, positioned on top followed by in-situ planting of various colourful drought tolerant plant species arranged in attractive patterns. Water retained by the trays during wet periods is returned to the planting media by capillary action during dry spells and drawn upon by the plants to sustain vigorous and healthy growth.

HDB Car Park – Punggol, Singapore

To facilitate planting on the RC rooftop of the Car Park to provide a Green Roof that is attractive and offers effective thermal insulation to reduce urban heat island effect.

VersiDrain 25P drainage and water retention trays were installed over the waterproofing membrane. Geotextile was then laid over the VersiDrain 25P and EnviroMix GR lightweight inorganic planting media positioned evenly on top followed by planting of various drought tolerant and colourful plant species arranged in attractive patterns. Water retained by the trays during wet periods is returned to the planting media by capillary action during dry spells to maintain healthy plants.

West Coast Plaza – Singapore

To provide modular vertical greening system for 4 in-door green walls at the car park on the 2^nd floor of the shopping centre.

Anchoring pilasters and a drip irrigation system to deliver water and nutrients to the plants were installed onto the 4 wall panels. Pre-planted VGMs, each comprising a geotextile bag filled with lightweight planting media and encased in metal support frames were mounted onto the pilasters. Artificial lighting was installed to supply the light source for sustaining plant growth in an indoor environment and a shallow metal trough placed beneath each wall to collect and drain away excess water.

Lot One Shopping Mall – Singapore

To provide modular vertical greening system for 3 free-standing decorative green walls at the void deck of the shopping mall.

Free-standing metal frameworks were installed in troughs and anchoring pilasters installed on both sides of each framework. VGMs, pre-planted in a controlled nursery environment were mounted to both sides of each framework enabling the free-standing green walls to be viewed and enjoyed from either side. Elements of design were also incorporated requiring the sides of each green wall installation to be covered with steel cladding and the troughs covered with granite pavers to conceal the base of the support framework with the addition of a precision water-jet fountain in one of the troughs.

Pasir Ris Park, Singapore

To provide slope stabilisation for plant media confinement and sub-surface drainage and water retention to enable planting on the RC pitch roofs of the activity shed cum shelter and toilets at the entrance to the Park.

VersiDrain 25P^® drainage and water retention trays were installed directly onto the RC roof tops and a geotextile filter fabric positioned over the trays. In addition to functioning as a sub-surface drainage, the network of cells in VersiDrain 25P® trays retain water which is returned, via capillary action, to the planting media during dry periods, helping to maintain and sustain healthy plants.

VersiWeb^® cellular confinement panels were then placed over the geotextile fabric within the raised curb borders of the roofs and the expandable cells filled with EnviroMix^® GR, a lightweight inorganic planting media. The honeycombed cells of VersiWeb® contain and confine the planting media on which locally-sourced drought tolerant plants requiring minimal maintenance were planted. VersiWeb^® uniformly distributes weight-bearing loads and prevents planting media and plants from being dislodged and sliding down the sloping roofs.

The green roofs blend into the green ambience of the Park and also help to keep the interior and activity spaces beneath them cool.

Aramsa Garden Spa – Bishan Park, Singapore

To facilitate planting on top of existing metal Corus Kalzip roof to provide an attractive green roof that will assimilate well into the natural ambience of the Park, serve as thermal insulation and also help to reduce noise transference during heavy rainfall.

To prevent plant media movement, aluminium battens were anchored onto the metal sloping roof and VersiCell drainage modules were placed between the metal ribs to provide an insulating barrier and a level surface for the subsequent installation of VersiDrain 25P drainage and water retention trays. A geotextile filter fabric was then positioned over the drainage and retention trays and EnviroMix GR lightweight inorganic planting media placed over the filter fabric. Locally sourced plant species selected for their hardiness, colour, height and ability to tolerate high tropical rainfall followed by hot and dry periods and requiring minimal maintenance were planted.
